And tomorrow: Mañana, soldaré con mucho cuidado en el taller. Four small moments, four tenses, one verb — that is how soldar sounds in real life.

Common mistakes with soldar

The errors learners actually make with soldar, each with the wrong form, the right form, and why the right form is right.

✗ Yo solda las piezas de metal.

✓ Correct: Yo soldo las piezas de metal.

The person matters: solda is the él/ella/Ud. form, while the yo form is soldo. Using the third-person form with yo is one of the most common beginner errors.

✗ Ayer yo soldo la tubería rota.

✓ Correct: Ayer yo soldé la tubería rota.

The present and the preterite are different tenses: soldo is happening now, while soldé is a finished action in the past. Use the preterite with ayer.

✗ Treating soldar and unir as identical in every context.

✓ Correct: Soldar means to weld, while unir means to join things together.

They overlap, but each has uses the other does not: soldar fits sentences such as Soldo las piezas de metal, while unir belongs in a different sentence. Check the meaning you want before choosing.

✗ Yo soy soldado la tubería rota.

✓ Correct: Yo he soldado la tubería rota.

Spanish perfect tenses use haber, not ser: he soldado, has soldado, ha soldado. Ser plus the participle makes a passive, not a perfect tense.

✗ De niño, yo soldé el marco de la puerta todos los días.

✓ Correct: De niño, yo soldaba el marco de la puerta todos los días.

For a repeated habit in the past, use the imperfect (soldaba), not the preterite. The preterite (soldé) is for one finished action.

Frequently asked questions

How do I use soldar in everyday conversation?

Start with the phrases in the examples above — especially the common combinations such as Soldo las piezas de metal and Solda la tubería rota. Use the present tense for habits and general facts, and the preterite for things that happened once. Say the sentences aloud until the forms feel automatic, then swap in your own details: your own town, your own family, your own routine.

What is the difference between soldar and unir?

Soldar means “to weld”, while unir means “to join things together”. They are related words that learners often meet together, but they are not interchangeable — use soldar when you mean “to weld” and unir when you mean “to join things together”.

Which tense do I need most with soldar?

The present tense, for habits, routines and general facts — that is where you will use soldar most. The preterite comes next, for things that happened once and ended. The examples on this page use both, plus the imperfect, the future and the present perfect, so you can see the verb across the tenses you actually need.

Is soldar formal or informal?

Soldar is neutral — it is used in both formal and informal Spanish, at home, at work and at school. There is no special formal version of it; the same forms work in a conversation with a friend and in a letter to a company. What changes is the situation, not the verb.
